# Redis Configuration with AOF (Append Only File) Persistence
# This configuration ensures data persistence across container restarts

# Enable AOF persistence
appendonly yes

# AOF filename
appendfilename "appendonly.aof"

# Set the fsync policy for AOF
# Options: always, everysec, no
# - always: fsync after every write (safest, slowest)
# - everysec: fsync once per second (good balance, default)
# - no: let OS handle fsync (fastest, less safe)
appendfsync everysec

# If AOF fsync is set to always or everysec, prevent fsync during a heavy write load
# Setting this to yes may improve performance by preventing fsync blocking
